UNDERFRAMING Fon-CARS.

SPECIFICATION 4forming part of Letters Patent N o. 774,222, dated November 8, 1904.

Application filed July 5, 1904.

To all whom t may concern:

Be it known that we, HENRY C. WILLIAMSON and HERMAN PRIEs, citizens of the United States, and residents of Michigan City, county of Laporte, and State oi' Indiana, have invented certain new and useful Improvements in Underframing for Cars, of which the following is a speciication and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to car construction, and has particular reference to certain improvements in under-frames ofthat character employed with box-cars, although it is not restricted in its use to cars 0i' this especial c ass.

The objects of the invention are to generally improve the substructure or underframe of railway-cars, and particularly with reference to the central sills and the manner of mounting the holsters, as well as to provide a strong and rigid chair or support carried by the central sills for supporting the end sills and dead-wood of the car-body.

The invention consists of the construction and arrangement of parts hereinafter particularly described, and designated in the appended claims :and illustrated in the accompanying' drawings, in which- Figure 1 is a longitudinal section of the underframe of a car constructed in accordance with our invention and partially broken away between the ends to facilitate illustration. Fig. 2 is a section on the line 2 2 of Fig. 1, the sides of the Jframe being broken away. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is an end elevation of the frame, and Fig. 5 is a perspective of one of the chairs designed to be secured to the central sills and employed to support the end sills and dead-wood.

In carrying out our invention wemake the central sills in sections, such sections terminatingat suicient distances apart to permit of locating the holsters between the adjacent ends of such sections, and tie these ends together in such manner as to secure the rigidity and strength of continuous sills and avoid- Serial No. 215,346. (No model.)

' ing the necessity of cutting through the sills to provide for the reception of the holsters when made of continuous lengths or of forming the holsters of two sections and riveting the sections to the sills.

Preferably each sill is made of three sections, such as the end sections 10 and an intermediate section 11. As shown in Fig. l, the adjacent ends of the three sections terminate sufliciently far apart to receive between them the holsters 12, and the two central sills are also spaced apart any suitable distance to receive between them the draw-hars. (Not shown.) A

The sill-sections 10 and 11 are preferably made of channel-shaped steel beams, having their flanges extending outwardly, as shown in Fig. 3, and are tied together in such manner as to render the sills exceedingly rigid and strong. To this vend we employ metal angle-hars 13, which bridge the space between the ends of the sections 10 and 11 and are riveted to such sections. As shown in Figs. 1 and 2, the angle-har associated with each sill is located on the outer face of such sill and is disposed with one of its leaves verticaLwhile the other leaf extends outwardly from the sill at the lower edge of the vertical leaf, suitable means, such as rivets 14, securing the sillsections and angle-bars 13 together.

The vertical leaves of the angle-har 13 are relatively narrow, and as these bars are located near the upper edge of the channelbeams forming the sills a suitable space under the bridging angle-bars and between the ends of the sill-sections is provided for the reception of the holsters. We also employ, in addition to the angle-hars 13, metal reinforcing-plates 15, located on the opposite sides of the sills from the angle-bars 13 and also secured by the rivets 14. A spacing ring or Washer 16, located between the vertical leaf of the angle-har 13 and the platel and secured by a rivet 17, serves to eliminate vibration at this point and strengthen the parts.

To impart greater rigidity to the sills, an

as by rivets 19, to the upper flanges of the adupper tie-plate 18 is employed and secured,"

jacent ends of the sections 10 of both sills and of the adjacent ends of both sections 11V of' the sills, thus bridging the bolster-space.

The bolster 12,which may be of any suitable construction, but which is preferably made wholly of metal and of the character shown, extends between the ends of the sill-sections. 1n the construction illustrated each bolster consists of a pair of substantially Z-shaped side plates or bars so disposed that the upper flanges 2O thereof extend outwardly,while the lower flanges 21 extend inwardly, the web 22 being vertical.

Located on each upper flange and extending longitudinally. thereof is a plate 23, the inner edge of which projects beyond the edge of the web 22. A cap-plate 24 connects the upper fianges 20, the parts being secured in assembled relation by means of rivets 25 passing through the horizontal flange of the angle-bar 13, the cap-plate 24, plates 23, and the flanges 2O of' the Z-beams. Suitable bolts 26 passing through the horizontal flanges of the anglebars 13, the cap-plate 24, and the projecting edges of the plates 22, furnish additional securing means, bolts being` here preferably employed in lieu of rivets, owing to the inaccessible location of the projecting edges of the plates 22.

rllie inwardly-extending iianges 21 of the Z-bars are secured together by a bottom plate 27, riveted thereto and extending the length of' the bolster. The bolster is secured at its bottom to each sill by a cross-plate 28, the ends of which are riveted, as at 29. to the lower fianges of the channel-beams of the sills, while rivets 30, countersunk in the plate 28, pass therethrough and secure the bolster thereto, as shown, the center bearing-plate 31 being' riveted to the bottom tie-plate 28.

L-shaped angle-bars 32, riveted to the inner faces of the vertical web of the channel-beams 10 and 11 and to the bottom tie-plate 28, are provided and located at opposite sides of the bolster, so as to abut against the latter, as shown in Fig. 1, thereby giving greater strength and rigidity to the structure and effectually bracing the bolster.

By means of the construction and arrangement of the parts described we provide an organization in which the center sills possess all the advantages of continuous sills, including rigidity and strength, and which obviates the objections to the continuous sill in the manner of mounting' and securing the bolster. Moreover, the sills may be made of shorter-length steel beams and are therefore cheaper of manufacture than the continuous-length sills.

Rigidly secured to the outer end of each sill-that is to say, the outer end of each beam 10-is achair designed to support and have sei l i not necessarily, made of cast metal and consists of a horizontal channel-shaped base 34, having its web vertical and its flanges extending outwardly, as shown in Fig. 4, its lower flange 35 being disposed in extension of' the lower ange of' the adjacent end sill-section 10, while its upper flange 36 is disposed in a plane below the upper iiange of the end sill-section and terminates in a vertical flange 37, extending above the upper flange of' the end sill-section. The flange 37 is provided with a lug 38, riveted to the adjacent end of the upper flange of the sill-section 10.

Each chair 33 is provided with a rearward extension or web 39, which is offset, as shown in Fig. 2, to receive the vertical web of the end sill-section l0, the inner face of the latter being iush with the inner face of' the web of the base 34, as shown in Fig. 2. The web 39 is riveted to the web of the sill end section 10, and the lug or cheek plates 40 of' the draftrigging are secured upon the inner faces of sill end sections and the webs of the bases 34 of the chairs. The horizontal and vertical flanges 36 and 37 of each chair provide an L- shaped seat whereupon rests the wood end beam 41, which is secured to such flanges by bolts 42, as shown in Fig. 1, while the deadwood beam 43 rests upon the outer ends of the chair-seats and is secured in position by bolts 44,passing therethrough and through the horizontal flanges 36 of the chair-base 34.

The nailing-strips 45, to which the flooring is nailed, are secured upon the upper flanges of the central-sill beam-sections, as shown in Fig. 3, and the draw-bar hanger or strip is secured to the beam 43 in any suitable manner, as by means of the bolts 44 and additional end bolts 46 passing through the deadwood.

Ve claim as our invention- 1.
